Announcing a new milestone for Sprint's four-month-old high-speed 4G LTE network, the carrier's CEO Dan Hesse recently revealed at the Goldman Sachs Communicopia Conference the sales of Sprint's LTE devices have hit the `one million' mark.

The disclosure, that Sprint - which has been expanding its lineup of LTE-capable devices since late April - has sold one million LTE devices to date, is an indication that the carrier's customers are quite satisfied with its LTE-capable offerings.

Although Hesse refrained from revealing the exact sales figures for each of Sprint's LTE-capable devices, a Fierce Wireless report has drawn attention to the fact that the Sprint CEO did mention that the Samsung Galaxy S III and HTC EVO 4G LTE were the key contributors to the carrier's LTE handset sales.

With Sprint having started selling the HTC EVO 4G LTE in May and the Samsung Galaxy S III in July, it is being speculated that these two handsets - supporting the carrier's high-speed wireless technology LTE or Long Term Evolution - together comprised for nearly 90 percent of the carrier's sales of LTE-capable handsets.

Incidentally, even though Sprint started rolling out its first LTE services in five cities in July, the carrier began selling LTE handsets - like the EVO 4G LTE - months before its network actually supported the service!
